Schema Previews

Schema previews let you try out new features and changes to our GraphQL schema before they become part of the official GitHub API.

During the preview period, we may change some features based on developer feedback. If we do make changes, we'll announce them on the developer blog without advance notice.

To access a schema preview, you'll need to provide a custom media type in the Accept header for your requests. Feature documentation for each preview specifies which custom media type to provide.

Note: The GraphQL schema members under preview cannot be accessed via the Explorer at this time.
